Microsoft also provides information to help customers prioritize monthly security updates with any non-security updates that are being released on the same day as the monthly security updates. Please see the section, Other Information.

Executive Summaries

The following table summarizes the security bulletins for this month in order of severity.

Cumulative Security Update for Internet Explorer (3183038)This security update resolves vulnerabilities in Internet Explorer. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Cumulative Security Update for Microsoft Edge (3183043)This security update resolves vulnerabilities in Microsoft Edge. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Microsoft Edge. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than users with administrative user rights.

Security Update for Microsoft Graphics Component (3185848)This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if a user either visits a specially crafted website or opens a specially crafted document. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Security Update for Microsoft Office (3185852)This security update resolves vulnerabilities in Microsoft Office. The most severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Security Update for Microsoft Exchange Server (3185883)This security update resolves vulnerabilities in Microsoft Exchange Server. The most severe of the vulnerabilities could allow remote code execution in some Oracle Outside In libraries that are built into Exchange Server if an attacker sends an email with a specially crafted attachment to a vulnerable Exchange server.

Security Update for Silverlight (3182373)This security update resolves a vulnerability in Microsoft Silverlight. The vulnerability could allow remote code execution if a user visits a compromised website that contains a specially crafted Silverlight application. An attacker would have no way to force a user to visit a compromised website. Instead, an attacker would have to convince the user to visit the website, typically by enticing the user to click a link in either an email or instant message that takes the user to the attacker's website.

Security Update for Windows (3178467)This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if an attacker creates a specially crafted request and executes arbitrary code with elevated permissions on a target system.

Security Update in OLE Automation for VBScript Scripting Engine (3188724)This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if an attacker successfully convinces a user of an affected system to visit a malicious or compromised website. Note that you must install two updates to be protected from the vulnerability discussed in this bulletin: The update in this bulletin, MS16-116, and the update in MS16-104.

Exploitability Index

The following table provides an exploitability assessment of each of the vulnerabilities addressed this month. The vulnerabilities are listed in order of bulletin ID then CVE ID. Only vulnerabilities that have a severity rating of Critical or Important in the bulletins are included.

How do I use this table?

Use this table to learn about the likelihood of code execution and denial of service exploits within 30 days of security bulletin release, for each of the security updates that you may need to install. Review each of the assessments below, in accordance with your specific configuration, to prioritize your deployment of this month's updates. For more information about what these ratings mean, and how they are determined, please see Microsoft Exploitability Index.

In the columns below, "Latest Software Release" refers to the subject software, and "Older Software Releases" refers to all older, supported releases of the subject software, as listed in the "Affected Software" and "Non-Affected Software" tables in the bulletin.

Affected Software

The following tables list the bulletins in order of major software category and severity.

Use these tables to learn about the security updates that you may need to install. You should review each software program or component listed to see whether any security updates pertain to your installation. If a software program or component is listed, then the severity rating of the software update is also listed.

Note You may have to install several security updates for a single vulnerability. Review the whole column for each bulletin identifier that is listed to verify the updates that you have to install, based on the programs or components that you have installed on your system.
